Specification of Letters Patent.

Application filed December 27, 1917. Serial No. 209,095.

To all whom it may concern:

Be it known that I, RICHARD FREDERICK GORDON, a subject of the King of Great Britain, residing at Liverpool, in the county of Lancaster and Kingdom of England, have invented certain new and useful Improvements in Typewriting-Machines, of which the following is a specification.

The present invention relates to improvements in typewriters.

An object of the present invention is to provide a typewriter which will be rigid and consequently durable and will have the minimum of parts and be of simple construction.

The invention is more particularly de-. scribed with reference to the accompanying drawings in which Figure 1 is a sectional elevation of a typewriter.

Fig. 2 is a perspective view of a detail.

The type keys 1, are pivoted at 2, and have pins upon them engaging the slotted end of a bell crank lever-3, which is con nected by a link 4:, to the outer end of a two-armed type bar 5, pivoted about a wire 6, of arcuate form mounted in a slot 7 in a notched guide comb 7 for the type bars.

The type bar 5, carries type 7 7 upon it.

The type bar 5, has a flat portion 27 upon it which, when the type bar reaches the position in which the type 7 a or 7 will strike the platen 17 will be substantially vertical. This surface 27, is adapted to engage the end of the universal bar 27 maintained normally pressed toward the left hand side of the type, that is to say the front of the machine by a spring 28 and sliding in guides in the case 32, which case has the comb 7 mounted upon it. As the universal bar 27' is pressed to the right of the figure against the action of the spring 28, its bent end 29, is adapted to abut as shown in Fig. 2, against an adjacent set screw on an arm 23 mounted on a spindle 14 adapted to oscillate about a vertical axis and having a beveled feed tooth 21, engaging the teeth 22 l 13. This spindle '14 may also be swung about its vertical axis by the operation of the spacing bar. The spacing bar 9', is carried upon a lever 15 pivoted about a spindle 16 and has a bracket 10 moving in the'range of a bent arm 11 on a horizontal spindle 12whichat its inner end has also anotherarm so that when the spindle 12, is oscillated about its horizontal axis by the depression of the spacing bar, it will move the arm 30, on the vertical spindle'l l, which will cause the feeding forward of the carriage 18,'in its guides 19, on the arm 20 in the usual manner.

The case 32 is provided with a spindle 33 having guides 34, 35, adjustable upon it to limit the amount by which it may be raised or lowered by means ofthe case shift key 42 mounted on the case shift lever 41, which has an arm 40, depressing the pivoted lever 36 about its pivot 37 by means of the roller 39 on the bracket 40. The end of the pivoted lever 36' is slotted and engages the pin 38 to depress the case 32, carrying the type bars, against a spring. (Not shown.) The comb 7 carries the usual pair of space .fingers 8, to secure the centering of the type bar as it strikes the platen 17.

' I declare that what I claim is 1. In a typewriter, the combination of a vertically disposed oscillatable post adapted to operate an escapement, a substantially horizontally disposed tappet on said post, type levers, bar adapted to be shifted horizontally by said levers and having an integral projection depending parallel about said post and arranged to be in position to operate said tappet when said bar is shifted horizontally irrespective of the vertical position of said bar.

2. In a typewriter, the combination of a vertically shiftable groove plate having a rearwardly extending bracket, a horizontally disposed universal bar mounted on said groove plate and bracket to slide in a horizontal plane thereon, type levers adapted to slide said universal bar, a vertically disposed oscillatable post adapted to operate an escapement, a horizontally arranged tappet therefor, said universal bar having a projection arranged to the rear of said.

bracket and transversely of said tappet, so as to be in position to operate said tappet when said universal bar is shifted horizontally irrespective of the vertical position of said bar.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
